Though born in Germany, Günter Müller has lived in Switzerland since 1966. From 1981 he has been playing a unique drum set with a mobile pick-up and microphone system of his own invention which allows hand-generated sounds on drums and percussion to be modulated electronically. Since 1998 minidiscs, and since 2002 an ipod, have been included in his electronic set. Nowadays he often plays ipod and electronics only.

Müller was a founding member of the trio Nachtluft, with Andres Bosshard and Jacques Widmer, a group that have created sound-installations and sound-architecture, and of the electronic quartet POIRE_Z with Erik M and Voice Crack. He has worked in a wide variety of contexts: solo; in ad-hoc groupings; and often in duo with, among others, Taku Sugimoto, Jason Kahn, Steinbrüchel, Norbert Möslang, Toshimaru Nakamura, Tomas Korber, Lê Quan Ninh, Keith Rowe, Erikm, Carlos Zingaro, Sachiko M, Michel Doneda and Fabrice Charles.
